Just as CEO JK Shin predicted, Samsung has announced its new Galaxy S 4 topped 10 million units sold in record time. That beats the 50 days it took the Galaxy S III to sell that many, a mark it took 5 months for the Galaxy S II to pass and 7 months for the original Galaxy S. Samsung has been able to crank up production and speed up worldwide rollouts for its increasingly popular flagship models, contributing to the rapidly increasing pace of sales. To help keep the sales channels flowing, Samsung also announced a few new colors on the way. Joining the existing White Mist and Black Forest models this summer are Blue Arctic and Red Aurora, followed later by Purple Mirage and Brown Autumn editions. Of course, the model many will covet is the one with stock Android announced at Google I/O, but that may depend on whether you want your customizations inside or outside.
